Answer:
(9/10)/(2/5) = ratio of work times
2 1/4 times as long
Step-by-step explanation:
<u>Given</u>:
2/5 hours work in the morning
9/10 hours work in the afternoon
<u>Find</u>:
an equation for how many times as long was afternoon work compared to morning work
the equation solution
<u>Solution</u>:
a/m = r . . . . ratio of afternoon work to morning work
(9/10)/(2/5) = r . . . equation
(9/10)/(4/10) = r
9/4 = r = 2 1/4 . . . solution
The builder worked 2 1/4 times as long in the afternoon as in the morning.
